Product information

Description

The KeySonic ACK-540U+ is a compact wired mini keyboard in black with an integrated Smart-Touchpad. It combines a space-saving mini form factor with a full-size layout functionality: an integrated numeric keypad can be activated via a function key, and a built-in touchpad with two mouse buttons replaces the need for an external mouse. The surface uses a matt SoftSkin coating and the keyboard features blue LED indicators for Caps, Num and Scroll Lock in a light‑stripe design. Keystrokes are quiet and provide tactile feedback thanks to X-Type membrane technology.

Advantages

The wired USB connection ensures a stable and reliable link to desktops or notebooks. The mini form factor saves desk space while keeping full typing functionality through an integrated numpad. The Smart-Touchpad and two mouse buttons allow cursor control without an additional pointing device. The SoftSkin surface and rounded design improve comfort during extended typing, and the quiet X-Type membrane reduces noise.

Suitable for

Office work on desktop or laptop computers
Users who need a compact keyboard with integrated numeric keypad
Environments where a quiet keyboard is preferred
Setups where an integrated touchpad replaces an external mouse

When it may not be suitable

The mini form factor may not suit users who require a dedicated full-size numeric keypad or a separate ergonomic layout. Gamers or users who prefer mechanical key switches may find the membrane keys less responsive compared with mechanical alternatives.

Key specifications

Connectivity: Wired USB 2.0
Keyboard form factor: Mini with integrated numeric keypad (activated via function key)

Touchpad: Integrated Smart-Touchpad with left and right mouse buttons

How to use

Connect the keyboard to a computer using the USB cable. Use the function key to enable the integrated numeric keypad when needed. Navigate and click using the built-in Smart-Touchpad and its left and right buttons. Typing is the same as on a standard keyboard, with quiet tactile feedback from the X-Type membrane switches. LED indicators show Caps, Num and Scroll Lock status.

What to consider before purchase

Whether a compact mini layout meets your typing and numeric-entry needs
If you require mechanical switches instead of membrane keys
Whether an integrated touchpad provides the pointer control you need
Compatibility with UK English QWERTY layout

Usage recommendations

For typical office environments, place the keyboard centrally in front of your monitor to make best use of the compact layout and built-in touchpad. Use the function key to toggle the numpad only when necessary to keep primary keys easily accessible.
